The laws of probability, my friend. The laws of probability and physics, dictating maybe a little chaos theory? And if you ignore our imminent oblivion, I would say it is, if you'll forgive me for speaking in perhaps the layman's terms: Bright and Beautiful.
In 2004, a fanartist named Vinson Ngo, a.k.a Bleedman, somehow got it into his head to draw a manga-styledMega Crossover with every popular cartoon he could think of, recent and past, and blend them all together for a Fan Webcomic centered around the three superhero tykes known as The Powerpuff Girls.The result was Powerpuff Girls Doujinshi (a.k.a. Powerpuff Girls D) which combines the universes of Cartoon Network and Nickelodeon as well as a few other outside sources and original material, and places them in a town called Megaville, a neighboring city of Townsville in this universe, where malevolent forces are poised to attack.Be warned, though — blood, death, and sexual themes are heavily featured, placing the characters in situations in which one wouldn't normally see them. The story itself is something of a Round Robin, heavily based on fan-input.Gained a massive following on DeviantArt (see Ngo's profile page) and won 2005's Web Cartoonist's Choice Awards for Outstanding Character Art and Outstanding Superhero Comic. Around 2007, Ngo moved the comic from DA to Snafu-Comics. Updates have been sporadic but recently pretty steady due to Ngo also working on the crossover fancomic Grim Tales from Down Below and his original series Sugar Bits. He also said to have took on another Snafu member's project, Invader Zim: Manifest Doom though has yet to work on it. He's a busy man.
Artifact Title: The Powerpuff Girls in the title. While the girls do make contribution throughout the series and are still the main characters, most plot centers around Dexter and other cartoon characters. Not even any of the girls classic rogues make any appearance other then Mojo. And the first story arc's bad guy was Mandark.
For Bell, it's losing anyone close to her. And don't even think about trying to lay a hand on GIR or she will end you.
Samantha doesn't take losing a tooth very well.
The Professor still flips out when it comes to parent-teacher conferences.
Big Bad: Dr. X, Vexus (although she is only seen for a short while, she could be considered a Big Bad because the Darkstar Council is made up of Cluster robots), and Mandark before he was revealed to be The Dragon for Dr. X.
Big Creepy-Crawlies: A number of the Cluster robots, specifically the majority of the Mooks who attack the science fair.
Big Damn Heroes: Jack, Courage, Dexter, and the Powerpuff Girls at various points.
Foregone Conclusion: Chapter 9 ends with the villains successfully detonating the Temporal Bomb and destroying all of reality. Chapter 10 explains how they did it.
Worse so when taken in conjunction with Grim Tales from Down Below, where you know the fate of a good fraction of the main cast. It's not pretty.
Foreshadowing: Toward the end of Chapter 2, Mojo Jojo is surprised to learn that Dr. X thinks the Powerpuff Girls are a bigger threat to his plans than the Justice League, Teen Titans, or Men In Black. Seven chapters later, Dr. X is proven correct in terms of the MIB's threat level.
Funny Background Event: While Bubbles is learning about Olga from Mandy, Billy and Ed are making a hill to sled down using Ed as surfing board... what did they make it out of? Chunkies.
There's this. Remember that PPG episode where Buttercup learned about the tooth fairy and started harvesting teeth from villains?
"Why is the security Question 'Cheese Omelet in French'?" "It's all I could say!" (Dexter's attempt to learn French left him only able to say "omelette du fromage" in one of the classic episodes of the series.)
There's a scene depicting several PPG episodes, inlcuding the Dynamo, Moral Decay, The Mane Event, Down and Dirty, Bubble Vision, and Sun Scream (although that last one was originally Nano of the North...)
Samantha using Jack's sword and to try and kill Blossom. It doesn't work because the sword doesn't harm righteous people which we learned when Aku tried it on Jack himself in Samurai Jack.
Power Creep, Power Seep: Most noticeable with the girls themselves, as they tend to be the ones being saved rather than the ones doing the saving. Any fights they are involved in almost always require some form of assistance to win.
Take That: At the former writer/editor, no less. This page calls out the idea of Bell, a central character, being a super-advanced robot, an idea originally tested by Bleedman in concept art and explored in the work of former PPGD editor and current After Birth writer Griddles. The comments seem to reflect the opinion of the other writers, who've had a noted difference of opinion with Griddles in the past and present.
Telepath: Ms. Honeydew is revealed to be one. Any fan of Dexter's Lab should know what this means is about to happen.
Your Mom: When the group is at the beach, this bit of dialogue comes up:
Mandy: Okay. If I'm bothering to be out here: the free food. Where is it? Olga: Where's your boyfriend Billy? Mandy: Dating your mom.
Wham Episode: Chapter 9. The Darkstar Council invades the science expo and succeed in setting off a Temporal Bomb.
Wimp Fight: As a shout out to the show, the final showdown between Dexter and Mandark begins with one of these. Then they whip out their Power Armor and begin beating the everliving crap out of each other.
